xVictron BMV-712 BLACK Smart Battery Monitor
The Victron BMV-712 BLACK Smart is a precision battery monitor designed for 12V, 24V and 48V battery systems. It measures state of charge, voltage, current, power, consumed amp-hours and time remaining, giving installers and system operators a clear, accurate picture of battery status. The integrated Bluetooth module allows wireless monitoring via the Victron Connect app on iOS and Android devices.
Key Features
- Monitors state of charge, voltage, current, power, consumed amp-hours and time-to-go on a single backlit display.
- Built-in Bluetooth Smart (BLE) for wireless connection to the VictronConnect app on iOS and Android.
- Measures a second voltage input, allowing simultaneous monitoring of a starter battery or solar input alongside the main bank.
- Configurable relay output that can trigger alarms or control external devices based on programmable thresholds.
- Compatible with all battery chemistries including lead-acid (AGM, gel, flooded) and lithium (LiFePO4).
- Supplied in black housing, matching black panel and switchgear installations.
- Data logging and historical trend data accessible through VictronConnect without additional hardware.
Product Overview
The BMV-712 uses a precision shunt (supplied in the box) to measure current flowing in and out of the battery bank. From this, it calculates state of charge as a percentage, consumed amp-hours and an estimated time remaining at the current discharge rate. Accurate state of charge tracking depends on correct configuration of battery capacity, Peukert exponent and charge efficiency factor. These parameters are set via the display or through VictronConnect, which also provides a clear interface for monitoring live data and reviewing historical logs.
The second voltage input is a practical feature for marine, motorhome and off-grid installations where a starter battery or auxiliary bank needs to be watched alongside the main house bank. The programmable relay can be configured to activate at a defined state of charge or voltage threshold, making it straightforward to wire in a low-battery alarm, a load disconnect signal or a generator start trigger. The relay is a dry contact rated for low-current switching.
Bluetooth connectivity is built in, so no additional dongle or interface is required. The VictronConnect app provides full configuration access and displays all monitored values in real time. The BMV-712 can also be integrated into a wider Victron system via a VE.Direct port, connecting to a GX device such as the Cerbo GX for centralised monitoring and data logging.

Installation Notes
The BMV-712 shunt must be installed on the negative side of the battery bank, with all negative loads and charge sources connected to the load side of the shunt. Incorrect wiring will produce inaccurate readings. The unit is suitable for installation by a competent electrician or qualified solar installer. For systems integrated into a wider off-grid or hybrid installation, connection to a GX device via VE.Direct should be carried out by an installer familiar with Victron system architecture. Battery chemistry parameters must be correctly configured after installation to ensure accurate state of charge calculations.
